To all whom it may concern,.-

Be itLknown that I, THEOPHILU'S VAN KAN- NEL, a citizen of theUnited States, and a resident of New York, in'the county of New York 5 and State ofNew York, have invented Acertain new and useful Improvements in Storm- Door Structures, of which the following is a specification.

My invention is an improvement in rotat- Io ing doors designed to prevent drafts of air and changes in temperature in office-buildings, hotels, and halls during frequent en- -trance and exit.

The object of my improvement is to pro- 15 vide a more satisfactory means for supporting the structure and for folding the wings to free the passage-way and enlarge the entrance.

I provide a doorway having opposite sides 2o in. the form of an arcor segment of a circle or polygon. The door is preferably composed of a series of radial wings united at a central line, so that they may be easily separated. I also provide a rotating elevated pivot or turn- 25 table and support from it a ceiling extending over the radial wings. This `ceiling is preferably eoextensive with the circle described by a rotating wing. I connect the outer upper edge of each wing by means of a pivot- 3o like connection to a point in this ceiling, and a corresponding point Ain the lower edge of each wing I connect to a corresponding point in the door. These two points of connection for each wing permit of separating the wings 3 5 vat a central line and folding them outwardly,

turning them on the described pivot-like connections at or near their outer edges, so that they may be lapped and folded against the doorways and the Vpassage left completely 4o free.- I provide tracks supported from the ceiling, there being one such tracsk foreach wing. A hook or suitable mechanical device is fixed to the upper edge of each wing, and this engages with the track, whereby the Wing 45' is movably supported when the doorsare disconnected at the central line, and the operation of folding them is proceeded with. When the doors areto be folded, the rotating ceiling is first locked in position by means of a 5o bolt and a socket, the latter being in a stationary portion of the structure in a predetermined relative positionwith respect tothe sockets in the floor, which receive the bolts in the lower outer edge of .each wing. By this arrangement the locking of the ceiling leaves the wings in position Atobe locked to the I ioor. For the purpose of supporting the rotating ceiling I connect the rotating turn-table and circumferential points in the ceiling with each other by meansof rods or braces, and for the :purpose of steadying the rotating ceiling I I rotating ceiling with the arc-shaped rails for vsupporting the wings. Fig. 5 is an enlarged View of the rotating support, ceiling, and means for uniting the wings on the central line. Fig. G is a detail showing the peripheral rail and rollers for steadying the ceiling and also the pivot connection between the exterior u'pper edge of a wing and the ceiling.

' l) is the doorway.

w are the wings of the rotating door. I have shown four wings 1r. These are united at a central line by means of pairs of tubular sections or ring-sections, each section having a fiange which is screwed toits wing. I have shownl eight of these sections arranged in two groups.. Onepair of sections are attached at at or near opposite extremities of each wing. The sections of each group are designated by the letters a, b, c,- and d. The group of sections d b c d at the upper extremity of the wings are connected together by means of the v ertically-reeiprocating bolt ll, which also enters the supporting-pivot I and ser-ves to unite the sections together and to the support. The group of sectionsa., b, c, and el att-he lower extremity are united by the verticallyreciprocating bolt Il", which also enters a IOC) 2 Y vassess socket 22 in the fioor and serves to hold the lower port-ion of `the door against displacement. There are two additional sections e and f, as shown in Fig. l,` for .the purpose of holding or retaining the bolts B and B' whe in their withdrawn position.

The pivot or turn-table P is supported upon v a roof R, and the support is iliade lrigid and of sufficient strength by the use of one or more girders of merchant iron, as lm..

C is the rotating ceiling, preferably circular and supported-on the pivot P. Braces h extend from the pivot P to peripheral points of the ceiling C and serve to impart rigidity. At the outer upper extremity of each wing fw there is a metal casting q fixed in position, and at a corresponding point in the ceiling C there is a bearing r of metal. The pieces q and r are united by a pivot p, which is loose and permits the free rotation of the wing w,

suspended therefrom. At the lower outer exi tremity of each wing w there is a bolt'19, engaging asocket 20 in the floor. In the ceiling C there'is a bolt 23, engaging asocket 24 in a stationary part of the structure, such as the dependingI cornice s.- 'lhe position of the socket 24-is such, with respect to the sockets 20 inthe fioor, that when the bolt 23 has been placed in its socket 24 each of the bolts 19 on each of the wings w will bo in position to engage with the corresponding socket 20.

Referring to Fig. 4, where the under side :of the ceiling is shown, there are a series ofk Arails 30, arc-shaped in outline, there being one rail 30 for each wing. These rails are fixed to the under side of the ceiling C.. On the upper endof each wing w there is a hook 3l, having a smooth flat surface riding on the rail 30. This is-clearly shown in Fig. 5, and

the object of the construction is to aord sup.

port to the wiugw when it is freed at the central line by the withdrawal'of the bolts B and B. lVhen the wings are so freed, they may be folded or lapped intothe position shown in dotted lines in Fig. 2, wherev they are out of the way in case it is desired to move a bulkystructure or goods of an'y description in or out, or to provide for free ventilation.

For the purpose of s teadying the rotating ceiling I provide a peripheral wooden rail N,

y which vfollows `the circumference of the ceiling and is fixed t-o the upper side thereof, and I fix a series of rollers n, which are preferably composed in part of rubber applied in a manner designed to deaden the sound of These rollers n are fixed to the interior of the depending cornice s and engage the rail N, substantially as shown.

What I claim, and desire to secure by Letters Patent, is-
